Description of Barium Fluoride Crystal

Barium fluoride, BaF2, crystal has good transmittance over a wide spectrum range, from 150 nm to 12.5 um. It has been widely used as windows, lenses, and prisms, particularly for ultraviolet transmittance. The highest quality BaF2 has been used for scintillation crystals. BaF2 can also be used crystal substrates for the epitaxial growth of thin films.
